You can cause inconsistency in the VLAN database if you attempt to manually delete the vlan.dat file. If you
want to modify the VLAN configuration, follow the procedures in this section.
Creating or Modifying an Ethernet VLAN
Each Ethernet VLAN in the VLAN database has a unique, 4-digit ID that can be a number from 1 to 1001.
VLAN IDs 1002 to 1005 are reserved for Token Ring and FDDI VLANs. To create a normal-range VLAN
to be added to the VLAN database, assign a number and name to the VLAN.
With VTP version 1 and 2, if the switch is in VTP transparent mode, you can assign VLAN IDs greater
than 1006, but they are not added to the VLAN database.
